Sun the sun is the closest star to earth and is the center of our

solar system. A giant spinning ball of very hot gas,the sun is fueled by nuclear fusion reactions.the light from the sun heats our planet and makes life possible.

mercury: mercury the planet nearest the sun ,is also the smallest
planet in the solar system.only slightly larger than the earth’s moon. Mercury;s surface is covered eith craters. This tiny planet does not have any rings or moon.

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days. The planet is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky, reaching an apparent magnitude of [13] −4.6, bright enough to cast shadows. Because Venus is an inferior planet from Earth, it never appears to venture far from the Sun: its elongation reaches a maximum of 47.8°. Venus reaches its maximum brightness shortly before sunrise or shortly after sunset, for which reason it has been referred to by ancient cultures as the Morning Star or Evening Star.

Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial [22] planets. It is sometimes referred to as the world, the Blue Planet, or by its Latin [note 6] name, Terra.

The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature.
Uranus is the seventh planet from the Sun. Named after the Roman god of war. Jupiter is classified as a gas giant along with Saturn. While only one-eighth the average density of Earth. Named after the Roman god Saturn. having surface features reminiscent both of the impact craters of the Moon and the volcanoes. Uranus is similar in composition to Neptune. Mars is the site of Olympus Mons.Mars is the fourth planet from the Sun and the second smallest planet in the Solar System. Saturn is a gas giant with an average radius about nine [12][13] times that of Earth. and both are of different chemical composition than the larger gas giants Jupiter and Saturn. and polar ice caps ofEarth. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System.Uranus and Neptune
Saturn is the sixth planet from the Sun and the second largest planet in the Solar System. and of Valles Marineris. as is the tilt that produces the seasons. valleys. one of the largest canyons.
. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth. as the iron oxide prevalent on its surface gives it a reddish [14] appearance. It is a gas giant with mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in the Solar System combined.
[15][16]
Jupiter is the fifth planet from the Sun and the largest planet in the Solar [13] System. deserts. with its [14][15][16] larger volume Saturn is just over 95 times more massive than Earth. it is often described as the "Red Planet". the second highest known mountain within the Solar System (the tallest on a planet). astronomers sometimes place them in a separate category called "ice giants". Mars is a terrestrial planet with a thinatmosphere. its astronomical symbol (♄) represents the god's sickle. after Jupiter. For this reason.

On average.1 AU.Neptune is the eighth and farthest planet from the Sun in the Solar System.
. It is the fourth-largest planet by diameter and the third-largest by mass. which [12] is 15 times the mass of Earth but not as dense. Named for theRoman god of the sea. its astronomical symbol is ♆. Neptune orbits the Sun at a distance of 30. a stylised version of the god Neptune's trident. approximately 30 times the Earth–Sun distance. Neptune is 17 times the mass of Earth and is somewhat more massive than its near-twin Uranus.
